Both the TPP and the TTIP are being promoted by globalists. They are opposed to small enterprise and are, in fact, intent on the destruction of nation states. Their ultimate goal is one world government: Totalitarian control of the planet. Thai farmers are very right to be concerned for their future. They do not register in the intended grand scheme of big government and multinational corporations.
These so-called "partnerships" are nothing more than an intermediate step towards a new world order run on communist lines. The individual will become irrelevant and the sovereign state obliterated together with democracy as a form of government.
The European Union is a living example of this.
